Anti Vibration Mounts

SM Mounts

Mounts for levelling, shock and vibration absorption

Farrat SM Spring Mounts are low stiffness anti-vibration mountings with adjustable levelling and damping control for efficient isolation of dynamic (active) machinery and protection of sensitive (passive) equipment and machinery.

High deflection helical steel springs are contained in stove enamelled aluminium housings to provide a robust and reliable low frequency isolator. The levelling-fixing screw with locknut are zinc plated.
Gunmetal versions of sizes suffix G on request.

Typical applications include:

Compressors and Pump Sets
Power Generating & CHP Units
Plinth isolation of industrial washing machines
Scientific & Test Equipment
Measuring Equipment
Engine Test Beds
HVAC

Suffixes:
- G Gun metal housing for marine and other hostile applications
- NB Without baseplate

Farrat SM spring isolators supporting and isolating a large air conditioning unit
